Asopus in Greek mythology is the name given to four different river gods that protected four respective rivers in Greece. As with all river gods, they were the sons of the TitansOceanus and Tethys. The best known of these river gods were Asopus of the river in Boiotia and of the one of Sikyonia in the Peloponnese. Most often, the tales for these two river gods were intertwined and considered the two deities as the same. Their daughters were called Naiads and were nymphs of the various springs in the areas where the rivers flowed.
